Secure Azure Virtual Network using Network Security Groups

The way that Network Virtualization is implemented in Hyper-V and subsequently in Microsoft Azure IaaS, enables explicitly the Routing between Virtual Subnets. This is the reason why the traffic between Virtual Subnets, that are part of the same Virtual Network, is unrestricted unless we have applied Network Security Groups.

Reserve external IP on Azure Cloud Service

When we create a VM on Azure, at the same time we create a Cloud Service. Later we can create more VMs on the same cloud service. Each cloud service has a unique Public IP. For as long the Cloud Service has at least one VS running this Public IP remains the same. If all VMs of a Cloud Service are off then the Public IP is released and next time the VM is powered on it will take a new Public IP.   Using PowerShell we can reserve a Public IP for as long as the Cloud Service exists, with or witho

How to create Transport Rules in Exchange Online and Outlook Rules and the difference

Using Transport rules, you can look for specific conditions in messages that pass through your organization and take action on them. Transport rules let you apply messaging policies to email messages, secure messages, protect messaging systems, and prevent information leakage. Many organizations today are required by law, regulatory requirements, or company policies to apply messaging policies that limit the interaction between recipients and senders, both inside and outside the organization.

Alter the Office 365 DirSync Schedule

The DirSync by default runs every three hours. And you will realized that there is no GUI way to change that. To change the sync interval we need to change a configuration file. 1. Go to the below directory on your DirSync Server: C:\Program Files\WindowsAzureActiveDirectorySync (there are two similar directories, one with spaces between the words and one without. We want the one without spaces) Here we will find the main executable of the DirSync Scheduler, the “Microsoft.Online.DirSync.Schedul

Create a Virtual Machine with Multiple NICs in Azure IaaS

Every time I present a session about Microsoft Azure IaaS, the most common question is about Virtual Machines’ capability of getting more than one Virtual Network Interface (vNIC). At TechEd Europe 2014, Microsoft announced support for multiple Network Interfaces (vNICs) in Azure VMs, as well as other additions to Azure Virtual Networks like Network Security Groups. Moreover, the capability of adding more than one vNIC to a Virtual Machine will enable Virtual Appliances scenarios like Firewalls
